The Andacollo Gold Mine, Chile
In 1990 and 1991 I was part of the team that carried out a full feasibility study for the Andacollo Gold Mine, near La Serena in Chile's IV Region. The mine was later placed into production and has since produced of the order of 800,000 ounces of gold.
This section of the site describes controversy estimating the ore reserves, that I personally experienced, and the subsequent history of the mine itself.
